Feature request; preparing routes through the cartographic application

[nicolas-heigvd]

As a manager in participation studies, I want to;

• prepare several routes using the cartographic application,
• to get the route, I want to
  • specify a starting and ending point in a first version
  • specify a starting, intermediate points, and ending point in a second version
• export these routes as KML / GPX file so that my participants can easily upload them elsewhere, such as a geoportal or a navigation application
